Abstract

Abstract

The booster charge structure has direct effects on the detonation wave propagation, the driven flyers and the shock initiation performance. To analyze the influence of the booster charge structure on the performance parameters of the flyer power, a numerical simulation scheme was designed based on the orthogonal test principle in view of the 3 structural parameters, including the flyer thickness, the charge diameter and the flyer height. The AUTODYN3D finite difference program was used to establish the corresponding numerical model, and the main charge structure parameters influencing the flyer velocity, momentum and kinetic energy indexes were obtained through statistical analysis of the simulation results. The analyses and results provide a theoretical basis for the design of similar booster charges.
